Connection
1. Connect the "X1S1" interface for the 24 V voltage supply to the industrial
power supply unit.
Use a 24 V industrial power supply unit acc. to DIN EN 60742, classification VDE
0551, for example "VAP01.1H-W23-024-010-NN" (parts number R911171065) for
the voltage supply.
For wiring connection terminals use copper wire only.
NOTICE
In this case an isolated power supply unit has to be used.
UPS
The display immediately darkens in the event of a power failure if
the operating display has been connected directly to the 24 V supply
voltage without using a UPS. The user cannot execute any actions
via the operating display during the shutdown of the control cabinet
PC.
If the operating display is connected together with the control cabi-
net PC to the "24 V Out" of the external UPS, the user still can ac-
cess the operating display during the shutdown in the event of a
power failure.

If the distance between VDP and control cabi-
net PC exceeds 50 m, equalizing currents may
flow when using a non-isolated power supply
unit as pin 2 is internally connected to the
housing.
